HTTP Headers as constants in stdlib

[kirans]

Thanks for the response.
Am aware of the requests, and httpie libraries.

I think I need to elaborate, on my original query.
I want to refer to the Http headers as constants, and not as strings. So, for example

headers.get(http.HOST)

. This will eliminate a class of typo errors, and also not require one to remember the exact spelling of the Http header. Should it be referer or referrer, and does case matter, etc.

Therefore, was wondering if there is a module, like the http one referred above, (stdlib or otherwise), that could help with this.
